Hi. I would like to create a pop up message that only displays if a specific field is blank based on a selection from the main table and remain hidden until this condition is meet. This can be a simple hidden text box until the customer is selected. Currently I have the detailed information page hiding if no data is part of the selected customer by using the =count(distinct"field name") expression and this works fine. Along with the page hiding I would like a pop up on another page to indicate that there is no related details for the selected customer.
